C++ Operators

C++ operators include arithmetic and bitwise with precedence.

Introduction to C++ Operators

Operators in C++ are special symbols or keywords that tell the compiler to perform specific mathematical, relational, or logical operations. They play a crucial role in manipulating data and variables in C++. This post will cover the various types of operators available in C++, including arithmetic, bitwise, and their precedence.

Arithmetic Operators

Arithmetic operators are used to perform basic mathematical operations. These include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). Here's a quick look at how they function:

Bitwise Operators

Bitwise operators are used to perform operations on individual bits of integer types. These include AND (&), OR (|), XOR (^), NOT (~), left shift (<<), and right shift (>>). These operators are particularly useful in low-level programming and performance optimization tasks.

Operator Precedence and Associativity

Operator precedence determines the order in which operators are evaluated in expressions. In C++, operators with higher precedence are evaluated before operators with lower precedence. Associativity defines the direction (left-to-right or right-to-left) in which operators of the same precedence level are evaluated.

Conclusion

Understanding C++ operators and their precedence is fundamental to writing efficient and bug-free code. Proper use of these operators can optimize performance and improve code readability. Practice using these operators in different scenarios to become proficient in C++ programming.
